Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. When this was noised abroad - If we suppose that there was a considerable peal of thunder, which followed the escape of a vast quantity of electric fluid, and produced the mighty rushing wind already noticed on Acts 2:2, then the whole city must have been alarmed; and, as various circumstances might direct their attention to the temple, having flocked thither they were farther astonished and confounded to hear the disciples of Christ addressing the mixed multitude in the languages of the different countries from which these people had come.
Every man heard them speak in his own language - Use may naturally suppose that, as soon as any person presented himself to one of these disciples, he, the disciple, was immediately enabled to address him in his own language, however various this had been from the Jewish or Galilean dialects. If a Roman presented himself, the disciple was immediately enabled to address him in Latin - if a Grecian, in Greek - an Arab, in Arabic, and so of the rest.
